1。引包

<dependency>
			<groupId>net.sf.dozer</groupId>
			<artifactId>dozer</artifactId>
			<version>5.5.1</version>
		</dependency>

2.建一個xml文件，copy_dozer.xml 其中如果有字段沒有對上，可以用field

<?xml version="1.0" encoding="UTF-8"?>
<mappings xmlns="http://dozer.sourceforge.net" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://dozer.sourceforge.net
          http://dozer.sourceforge.net/schema/beanmapping.xsd">
	<!--客戶模塊 -->
	<mapping>
		<class-a>com.banksteel.openerp.customer.vo.CmCustomerVO
		</class-a>
		<class-b>com.banksteel.openerp.customer.api.entity.CmCustomer
		</class-b>
	</mapping>

　　　　　　<!-- 財務管理模塊 -->
　　　　　　<mapping>
　　　　　　　　<class-a>com.banksteel.openerp.finance.vo.FmReceivablesRecordVO
　　　　　　　　</class-a>
　　　　　　　　<class-b>com.banksteel.openerp.finance.api.entity.FmReceivablesRecord
　　　　　　　　</class-b>
　　　　　　　　<field>
　　　　　　　　　　<a get-method="getApplyTimeToLong">applyTime</a>
　　　　　　　　　　<b get-method="getApplyTimeToString">applyTime</b>
　　　　　　　　</field>
　　　　　　</mapping>

</mappings>

3.建一個公共方法類 BeanFactory.java

package com.banksteel.openerp.commons.dozer;

import java.beans.PropertyDescriptor;
import java.io.InputStream;
import java.util.HashMap;
import java.util.Map;

import org.apache.commons.beanutils.PropertyUtilsBean;
import org.dozer.DozerBeanMapper;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class BeanFactory {
	private static DozerBeanMapper dozerBeanMapper;
	private static Logger logger = LoggerFactory.getLogger(BeanFactory.class);
	static {
		dozerBeanMapper = new DozerBeanMapper();
　　　　　　　　　　// 這裏加上要引人的xml文件
		String[] pathes = { "admin-dozer.xml", "customer-dozer.xml", "facade-dozer.xml", "finance-dozer.xml",
		        "log-dozer.xml", "mbpm-dozer.xml", "mobile-dozer.xml", "purchase-dozer.xml", "quartz-dozer.xml",
		        "repertory-dozer.xml", "sale-dozer.xml", "system-dozer.xml", };
		try {
			for (String path : pathes) {
				InputStream inputStream = null;
				try {
					inputStream = Thread.currentThread().getContextClassLoader().getResourceAsStream("dozer/" + path);
				} catch (Exception e) {
					logger.error("dozer文件不存在：" + path);
				}
				if (inputStream != null) {
					dozerBeanMapper.addMapping(inputStream);
					inputStream.close();
				}	
			}
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

	public static void convert(Object source, Object target) {
		dozerBeanMapper.map(source, target);
	}

	public static Map<String, Object> bean2Map(Object obj) {

		Map<String, Object> params = new HashMap<String, Object>(0);
		try {
			PropertyUtilsBean propertyUtilsBean = new PropertyUtilsBean();
			PropertyDescriptor[] descriptors = propertyUtilsBean.getPropertyDescriptors(obj);
			for (int i = 0; i < descriptors.length; i++) {
				String name = descriptors[i].getName();
				if (!"class".equals(name)) {
					params.put(name, propertyUtilsBean.getNestedProperty(obj, name));
				}
			}
		} catch (Exception e) {
			e.printStackTrace();
		}
		return params;

	}
}

　4.復制。把一個對象裏面的值復制到另一個對象裏面

BeanFactory.convert(cmCustomerVO, cmCustomer);

用dozer實現兩對象之間的復制
